` To 'cI/,ZZ whom it may concern:

Be it known that I, ARTHUR M. HAMILTON, a Citizen of the United States,residing at Fall iver, in the County of Bristol and State of '5Massachusetts,have invented certain new and useful Improvements in Loomsfor Weaving Bordered Fabrics; and I dohereby declare the following to beafull, clear, and exact description of the invention, such as willenable othxo ers skilled in the art to which it appertains to make anduse the same.

This invention relates to certain new and useful mechanism applied tolooms for weaving cords in fabrics for making check goods I orhandkerchiefs with corded borders. Such goods have heretofore been wovenon a loom having a dobbyjhead, the ordinarypattern`` chain', and otherattachments, which make the mechanism expensive as to first cost andalso zo comparatively expensive in Operation.

The object of my invention is to do away 'with the dobby-head andprovide mechanism at a greatly-reduced cost which will effect- Y ivelyoperate to Weave a corded border in a handkerchief or "cords throughoutthe Whole fabric to make check goods; also, to enable the operator Orattendant to Weave a given number of yards of fabric lWith lessexpenditure of time and labor than Would be required 3o in the use ofthe (lobby-head. g

My invention comprises certain improved devices and mechanism forcontrolling the shedding of the Warp-threads and also for regulating thetake-up motion, the shedding mechanism and take-up motion beingsynchronouslyoperated, stopped, or started for producing the desiredcorded border or corded effect throughout the fabric in the manufactureof check goods. 4o The matter constituting my invention will be detinedin the claims.

I will now describe thedetails of construction and arrangement of thebest embodi- Vment of my mechanism by reference to the accompanyingdrawings,'in Which- Figure 1 represents av front elevation of I partoff'a loom' containing my devices. Fig. 2 represents an end elevationthereof. Fig.

l 3 represents a transverse sectional elevation -shown in Fig. 1.

showing part of the take-up mechanismnotgo Fig. 4 represents a sectionaldetail'view, on enlarged scale, of the mechanism of the take-up motion.Figs. 5an`d 6 rep-V resent elevations of certain devices at the lefthandend of the loom. Figs. 'Zand 8 show cer- 55 tain detail Views of partsshown in Figs. 5 and 6. Fig. 9 representsa transverse section throughpart of the disk-gear shown in Figs. 5 and '6. Figs. 10 to 17,inclusive, represent detached detail views of the pattern-chain 6omechanism. Figs. 18, 19, and 2O represent detail views of the cams onthe cam-shaft and operating mechanism therefor.

The mechanism Of the take-up motion at the right-handlend of-the loom isshown in Figs. 3 and 4 and is operated in the usual lnanner from thecrank-shaft GO, which is 1 connected by link 61 to the lay-sword 63,-which supports the lay 62. 1 I

The take-up pawl 2 is hingedl toa bracket 7o 1, which is bolted to thelower end of the'V laysword and engages at its outer hooked end with theratchet-wheel, which, together With a spur-gear or piniona, is mountedon the stud-shaft 3b, secured to the loom-frame A. 75 The pinion 3ameshes With the spur-Wheel A, mounted on shaft 5 of the cloth-roll,which is journaled in the usual mannerin the frame A. A pawl 6, pivotedto a pin or stud Ga, se-

'cured to the frame, engages with theteeth 8o On the ratchet-Wheel 3 topreventit from running backward.

The paWl 2 is ordinarily held in engagement with the teeth of wheel 3 bymeans of spiral spring 8, attached at one end to thel pawl and at theother end to the frame Ai When it is desired to put more than one pickinto the fabric, as when a cord is made, the gearing of the take-upmotion is stopped by means of strap 7, attached to pawl 2 and 9o passingdown under pulleys 7 and thence up to the lifting-lever 36 in thepattern-chain mechanism. At the proper moment lever 36 is lifted by oneof the balls in the patternchain, thus pulling on strap 7 and holding 95pawl 2 away from the teeth in Wheel 3.

I will now describe the devices at the lefthand end of the machine forbringing into and the harnesses lat rest the required number of picksmay be put in to form a cord, as

determined by the position of the balls iu the pattern-chain.

lIO

At the left-hand'end ofthe loom there is secured to the'end of shaft 5 atoothed gear i 9,'which meshes withthe disk gear 10, Figs. v5 and 6,supported on a stud-shaft 10', projecting from the frame A, as shown inFig. 1. The disk gear 10 is provided at the outer side near theperiphery with a circular dovetail vprojection as shown inFig. 9, andsuch projection is provided with an interior notch 10b, as shown inFigs. 5'and 6. zo

The dogs 11, having transverse dovetail grooves 11a, are

inserted at the notch 10b ontol the dovetail projection 10, and may beadjusted thereon in any desired position and held in place by the screws12, bearing upon the face of the projection'lOa, as shown lin Fig. 7. Bymeans i of the dovetail joint, made as above described,

the dogs may be readily adjusted in any desired position on disk gear 10and serve to l regulate the length of the pattern in the fab SOP ric.Below-the disk gear 10, Figs. 2, 5, and 6, the bent lever 13 ispivotally connected by pin 1 3Ytoalug or bracket 13C on the frame,

and to' its opposite end is attached. a spiral spring 14, Fig. 2, whichis also attached to the frame for supporting the lever in the desiredposition. Lever 13 is also provided with an-upwardly-projecting'horn13", which in practice is engaged by the `dog 11 for depressing thelever, as in Fig. 5. When one of the dogs 11 passes olf from horn 13b,the lejver is again raised by spring 14. A wire 15 connects at itslowerend with lever 13 and extends upl to the pattern mechanism, where itconnects with pawl 29, Figs. 11, 12, 13, and 15, for lowering said pawlto engage with the teeth of ratchet-wheel 31 when the lever 13 islowered or raising said` pawl to disengage it from the teeth of saidwheel when the vlever 13 is raised. Near the outer end of 'awl 29 isconnected an eye 30, Fig. 12, through which passes wire l5. The pawl isthus caused to engage with and slide on the wire when it is raised andlowered, as illustrated in Figs. 13 and 15.

I will now describe the mechanism for driving the pattern-chain, andthereby operating certain lifting-levers 36 and 3 7, by means of whichthe take-up motion' may be thrown out of gear and also the cams whichoperate the harnesses may lat! the same time be thrown out of gear, sothat the take-up motion and the shedding operations may be temporarilystopped while the desired number of picks areput in to form a cord inthe fabric.

Referring now to Figs. 1 and 2 and the detailviews, Figs.`10 to 17,inclusive,tl1e ratchetwheel 3 1 isprovided with a long barrel orsleeve-shaft 31a, which is mounted upon a around which passes strap orring 23, havingv connected with it the connecting or drivmg rod 23a,which at its upper end 'connects by To the left-hand end of a pin 2Swith the slotted arm 27 The pawl 29 is also pivotally connected by saidpin 28, so that its free end may engage the teeth of ratchet-wheel 31.Motion imparted to the driving-rod 23a by the eccentriccaus'es the arm27 to move in the arc of a circ'learound ratchet-wheel 31 and when the'pawl 29 is in engagement with the teeth thereof to partially revolve'said 'wheel at every upward stroke of rod 23a. Since the notchedpatternwheels 32 are secured to the sleeve-shaft 31,

they are turned with the 'ratchet-wheel and Y carry forwardpattern-chain 33 with its balls 34. The lifting-levers 36 and 37 arepivotally connected at' their rear ends to a studshaft 35, projectingfrom a bracket on the frame, and rest in an inclined position upen thechain above the pattern-wheels 32, as clearly shown in Figs. 16- and 17.A bent lever 26, Fig. 10, is also'connected to shaft 35 andis provided.at its inner end with a roller 26a, adapted to bearin the notches ofthe check-wheel 25, and is connected at its outer end by means of aspiral spring 50 to an arm 51, secured to the frame. Thespring 50presses the roller 26 into a notch of Wheel 25, so as to hold the Wheelswhich 'are attached to* the sleeve-shafts 31 from revolving, except whenthe ratchet-wheel is `caused torevolve by engagementof pawl 29. Anadjustingwheel 64, Fig. 1, similar in shape to the check- Wheel, is alsosecured to the sleeve-shaft 31" and. is used to turn-the patternmechanism by hand when adjusting it.

Tothe inner end of lever 37 is con'neeted a wire 21, which connects atits lower end with the bell-crank 20 on pin 20, which connects at itsother end by means of rod'53 with the clutch-lever 54 for operating theclutch on the cam-shaft, as shown in the detail views, Figs. 18 and 19.i

The cams 41 are loosely mounted on the cam-shaft 38 and are held inposition by the collars 42 and 43, and said cams are suitably notchedfor engagement with the clutch 40 and the catch 56a. The clutch 40 isconnected with the cam-shaft by means of a feather or spline 39. Theclutch-lever54 and the catchlever 56 are pivotally connected ata and bto the feet or licor brackets 46 and 47, and said ylevers are pivotallyconnected one to the IIO other 5." spiral spring 57 connects with thecatch-lever 56 and also with the iioor o'rbase plate oftheloom forpullingl catch 56a"-of said 'lever tout of engagement with the camandat'thef'same time moving the clutch-lever54 and the clutch 40 intoengagement withthecanifasfshown in Fig. 18.

As heretofore rexpla`i`ried,"ithe strap 7, which connects with thetake-up`pawl 2 and passes the fabric to form the desired cord.

The operation of 'myldevices is very simple and practically automatic,so that no extra labor or time is required of `the attendant foroperating the loom to Weave a bordered fabric. Before commencingtheweaving operations the balls Will be properly placed in corded border.

the pattern-chain to produce the desired in the desired position tothedisk gear 10 to act at the intervals of time for bringing the patternchain and mechanisminto operation to produce the desired :corded border.The number of dogs 11 and their relative positions on the disk gear 10may be varied according to the variety or style of corded borderdesired. When one of the dogs 11 passes into contact with the horn13b,fthe lever 13 vvill be depressed, thereby pulling down the Wire orrod 15 and engaging paWl 29 with the teeth of the ratchet-Wheel 3l. Theeccentric 22 being in continuous operation and its driving-rod 23 inconnection with the arm 27, the ratchet-Wheel 31 Will now be revolved,causing simultaneous revolution of the notched pattern-Wheels 32 andcontinuous movement of the pattern-chain 33. When the balls 311 of thepattern-chain pass over the Wheels, they will raise the levers 36 and37, causing the strap 7 to pull down the take-up pawl 2 and the Wire 21to disengage clutch L10 fromthe cams 4l, thus stopping the mechanism ofthe take-up motion and the harnesses While the desired number of picksare put into the fabric to make the desired cord. When the dog 11 passesoff from horn 13", lever 13 will again be pulled up by its spring 14,thereby raising the rod or Wire 15 and lifting pawl 29 out of engagementWith the ratchet-Wheel 31, as shown in Fig. 15, thus stopping the motionof the pattern mechanism. So soon as the balls 34 pass of from thepattern-Wheels 32, levers 36 and 37 Will drop onto the chain, as shownin Fig. 16, and the straps 7 will be released, permitting take-up pawl 2to be again pulled by spring 8 into engagement with ceases 1. ,Y

The dogs 1l are also secured- Y thefratIchet-wheel 3, and Wire 21 willbelowered, permitting the clutch 40 to be pulled by spring 57' intoengagement With the cams, so thatplain Weaving of the fabric is againresumed? When clutch 10 is pulled out of engagement with the .cams 4,1,as above described, thev` catch 56@ is at the same time pulledintoelngagenlent with the cams for preventing them from turning outioftheir proper position'- In order to prevent the driving mechanism whichruns the pattern-chain from stopping on a ball, thus holding the shedopen when not desired,l provide a safety device, consisting ofasafety-motion Wheel 17, Figs. 5, 6, 7, and 8, mounted on pin 19, held bybracket 18 and connecting by a strap 16 with lever 37.

The Wheel 17 is provided at its periphery with -a horn 17 a, adapted tobear upon lever 13, as shown in Figs. 7 and 8. A ball of thepattern-chain being on wheel 32 it holds lever 37 in the raisedposition, and thereby the strap 16, attached to said lever,will pullupon Wheel 17, causing :its horn 17 to bear upon lever 13 and. hold itdown, as shown in Fig. 8, until the said ball has passed off from Wheel32. Evidently this safety mechanism will thus act to keep thepattern-wheels in motion till the balls have passed off from them, eventhough the dog ll-has passed off from horn 13b of lever 13. e

Motion may be taken from the cam-shaft instead of the crank-shaft todrive the pattern mechanism, but in this case the control is limited totwo picks to each revolution.
